To all whom "it may concern.'

ABe ita-known :that LJosEPn- RAsHKIN, a subjectloff'the Czar ofltussia, and a resident Y inthe county of New ,York-andState o'f New York, have in- I vented certain new and useful Im rovements in Doors for llevatorShafts', ofw lich the following is a-speciication.

lv'lyn'yention relates to improvements in doors 'for` elevator-shafts of 'the general type f disclosed in .my prior gpatent ..No. 756,524,

- or two sections ofI one door, are-slidably sulpdated April 5, 1904, whereina pair ofdoors,

Both, objects of my :invention referred te are obtained by means-of the novel features of construction and combinations of arts as hereinafter. set forth in detail and polnted :Referringnowto the acconianying drawcation, Figure lis a vertical section throng?)i-part of a1i' ele vator shaft, showing athe v ment'- therein of 4anlelmrator .and pair fof -doors,. the llatter :being vin v'sectionf andfin` tionfor use .in-easezof `insu'llicieht space bebetween adoor-and one of its trackrails, the latter u being sectioned. view-in `front-elevatiolrzof a portion of the Fig..f6' is a section .and 3,13', apair offdoorssupported to slide -m the saldshaft' in apositionbetween the wall rtl iereof and the elevator. .These doors relative arrange- Fig. -5 -is a detail opened gposition. Fig'. l21isa section 5thro'ugh'y line .2-'-.2 of FigfL Figi 3 is gadetail View' inside elevation of -.a -doorfand `one 'of itsV track rails showingf my :improvedw censtruc- 3, 3'., 1in the, present case, are provided at `theihedges with .groovedfplatcs 4 which engage with suitable Itrack-rails '5'. carried by `merle-plates (i 'which-arc suitably attached to the inm-.r'wallsof'thc shaft,.in' the usual manner. ln order Athat each pair of doors may-nove lin unison and counter-lmlance 3cm-.h other,the-saine-will,preferably be ronnet-.ted by:assuitable eableoperating over a stationary pulley (not shown) in substantially the same manner as disclosed in my said prior patent No. 756,524.

'lhe doors 3, 3', may be of any suitable or desired construction, but the saine will preferably comprise la-wooden body portion 7 having a tin or other metallic covering 8 and being framed in at its edgesfby angle irons or lates 9, the latter being secured to'the said body portion 7 of the doors by suitable fastening means, such as the'bolts 10. Inaceordaniie with my present invention,

I provide a metallic filling or bridge plate 12 for occupying the space betweenithe elevator-floor 2 and the door-sill 1 when thc l0 doors are opened which may be supported and o erated in any suitable manner to be mova )le to rand from its said operative Iposition upon the opening and elosingof the doors, the said filling or bridge plates` in the 15 resent ease being shown as resting and aving its 'bearing upon the horizontal flange 9" of the angle-plate -9 at the upper edgevof the lower door section 3, whereby it will be supported and operated' by the latter. This filling or bridgefplate l2.may be scoured in position on tlie door in any suitable manner, the same in-the present ease being the'horizontal flange of an angleplate 12 which embraces that corner of the doon oppositethe angle-plate 49 and being secure( in position on th'e door by the bolts A 10,' as indicated, by dotted lines in Fig.. 6.

The lower door 3 may be supported inits lowered open position with the filling or 3f) bridge plate 12 filling the-space between 'the' elevator floor 2' and the door-sill 1f', as shown in'v Fig. 1, by any suitable means, but

in the present ease I have provided the vcr-- tical flange 9 of the angle plate, 9 at the up.

per edge of said-door with an extension"\`14 at eah end'thei'eof whichiare ada tedl to engage with-suitable stops when tie door has reached its lowest limit of movement, the

vsaid stops in the present ease being formed 40 by plates 15 secured to the trackrails 5 with one edge extending into 'thepath 'of .niovement of the said extensions 14, as shown' in Fig. 4. By reason of the stopextension 14 being connected with or formed upon the angleplateg as described, the sup ort al"- forded by said angle-plate-Q to the illing or bridge plate 12 is direct and positive, and any wear or strain on the door roper caused by the passing or.l trucking o heavy loads over the bridgeplate is thereby avoided:

When the space between the door-ways on .erent floors is sufficient foi the complete opening of a pair of doors on one floor without interference with those on the adjacent l floors, each of the two doors of each air will be formed in one part oisection as s iowii in Fig. 1. When, however, the space between the door-ways is iiisiillif-.ientthe lower door will be formed with a lower hinged section l 3, and suitable means will be provided for engaging with said hinged section upon the lowering of the door to deflect it inwardly from its normal ath of movement, as shown. in Fig; 3, where y it will be caused to move downwardly past and behind the top ofthe 2 l 'y :571,736v

| adjacent door 3? on the next lloor only tlic upper edge of 'which is shown in Fig. 4. Any suitable means may be provided for so deflecting-the said hinged door-section from its normal path of movement,l the means herein shown comprising a cam block 1,6 secured to a plate 17 which is attached to the railearrying late 6.

What claim is:

1. The combination with an elevator shaft having a ,door opening in the wall thereof and an elevator ear movable in the shaft., of a door supported. to slide in said shaft between the wall of the latter and the door aml movable there with and -ineansffor arresting and rigidly supporting the bai' in register with the building-floor ii'hereby said bar will provide a fixed bridge between the car-floor and the building-floor. 85 2. In combination with an elevator shaft having ya door-opening 'in tbc.wall thereof, and an elevator movable in said shaft, of a door supported to slide in said shaf'tbctwcen the lwall thereof and the elevator and being movable down'ii'airlly from its normal closed position opposite the door-opening to a position with its Avupper edge substantially flush with the door-sill, the saiddoor being provided at its `up er edge witliaii angle plate the horizontal ange of which forms frt of the upper edge of the door and the vertical flange of which isextended at its oppositee'iids beyond the sides of' the door, and means for engaging with the said end extensions of the angle-plate for suppoxtl'iig the door in its lowered position.
